ΑΠΛΟΥΝ

LEXARITHMOS 631

Simplicity as a fundamental concept in ancient Greek thought, ranging from Presocratic philosophy to mathematical precision. The term ἁπλοῦν, "the simple," stands in contrast to "the compound" (σύνθετον) and emerges as the basic unit or indivisible essence. Its lexarithmos (631) suggests unity and primordial form.

Definition

The term ἁπλοῦν (neuter of ἁπλοῦς) describes that which is single, indivisible, or uncompounded. In ancient Greek philosophy, the concept of simplicity was central to understanding the nature of reality. Presocratic thinkers, such as Parmenides, sought the simple, unchanging essence behind the apparent complexity of the world.

In mathematics and geometry, ἁπλοῦν refers to a unit or element that cannot be further analyzed. For instance, a straight line is considered simpler than a curve, or a point as the simplest geometric entity. This usage underscores the quality of ἁπλοῦν as a fundamental, primordial form.

Beyond philosophy and mathematics, ἁπλοῦν can also refer to ethical qualities, denoting sincerity, integrity, and the absence of deceit. An «ἁπλοῦς ἄνθρωπος» is someone who is straightforward, honest, and unpretentious. This meaning emphasizes internal coherence and the lack of complexity in character.

The contrast of ἁπλοῦν with σύνθετον (compound) is crucial. The simple is that which is not composed of parts, or at least cannot be separated into them. This distinction formed the basis for many metaphysical and epistemological discussions, particularly in Aristotelian thought concerning substance and form.

Etymology

ἁπλοῦν ← ἁπλοῦς ← ἁπλ- (root connected to ἅμα "together" and ἅπας "all, whole")
The root ἁπλ- is an Ancient Greek root belonging to the oldest stratum of the language, associated with the concept of unity and aggregation. From this root derive words such as ἅμα ("together, at the same time") and ἅπας ("all, every single"). The meaning of "single" or "indivisible" developed from the original idea of "one" or "whole."

From the same root also derive words denoting multiplicity, such as διπλοῦς ("double") and πολλαπλοῦς ("manifold"), where the root ἁπλ- functions as "fold" or "turn." The semantic evolution from "unified" to "simple" (as uncompounded) is evident throughout the family of derivatives.

Main Meanings

  1. Single, unitary, indivisible — The primary meaning, that which is not composed of parts.
  2. Uncompounded, not manifold — In contrast to σύνθετον or πολλαπλοῦν.
  3. Sincere, straightforward, unpretentious — Referring to character or conduct.
  4. Pure, unadulterated — Without mixtures or complications.
  5. Simple in appearance, plain — Without ornamentation or superfluous elements.
  6. Mathematical unit, element — The basic, indivisible constituent (e.g., point, line).
  7. Philosophical essence — The primordial, unchanging principle (e.g., Parmenides).

Word Family

ἁπλ- (root meaning "single, fold")

The root ἁπλ- is fundamental in the Greek language, connecting the concept of "one" or "single" with that of a "fold" or "turn." From it arise words denoting both simplicity (as uncompounded) and multiplicity (as multiple folds). The meaning of simplicity emerges from the idea of being unfolded, a unitary form, while multiplicity is expressed by adding prefixes that indicate the number of folds.

ἁπλοῦς adjective · lex. 781
The adjective "simple, single, uncompounded, sincere." It is the basis for the neuter ἁπλοῦν. Widely used by Plato and Aristotle to describe the essence of things.
ἁπλότης ἡ · noun · lex. 689
The abstract concept of simplicity, sincerity, integrity. In the New Testament, «ἁπλότης καρδίας» denotes unfeigned faith and generosity (e.g., Rom. 12:8).
ἁπλόω verb · lex. 981
Meaning "to simplify, make simple" or "to unfold, open out." The latter meaning highlights the root's connection to the idea of a "fold," where the simple is that which is not folded.
ἁπλῶς adverb · lex. 1111
"Simply, plainly, without complications." Used to denote straightforwardness or the absence of superfluous elements. In Aristotle, «ἁπλῶς» means "absolutely, unconditionally."
διπλοῦς adjective · lex. 794
"Double, twofold." Derived from δίς ("twice") and the root ἁπλ-, indicating two "folds" or "turns." It directly contrasts with ἁπλοῦς in terms of unity.
πολλαπλοῦς adjective · lex. 991
"Manifold, multiple." From πολύς ("many") and the root ἁπλ-, it denotes the existence of many "folds" or manifestations. Used to describe complexity.
ἁπλοϊκός adjective · lex. 481
"Simple-minded, naive, guileless." A later meaning developed from the idea of simplicity of character, implying a lack of cunning or complexity in thought.

Philosophical Journey

The concept of ἁπλοῦν permeates ancient Greek thought, evolving from the cosmological quest for unity to the ethical simplicity of character.

6th-5th C. BCE
Presocratic Philosophers
Parmenides and Zeno explored the concept of the One as a simple, unchanging reality, contrasting it with the complexity of sensible phenomena.
5th-4th C. BCE
Plato
In works like the «Phaedo» and «Republic», Plato uses ἁπλοῦν to describe the immortal soul or the Forms as simple and immutable entities, in contrast to complex and perishable bodies.
4th C. BCE
Aristotle
In «Metaphysics» and «Physics», Aristotle analyzes the distinction between simple (ἀπλά) and compound (σύνθετα) bodies, elements, and concepts, establishing scientific and metaphysical terminology.
3rd C. BCE
Euclid
In his «Elements», Euclid employs the concept of simplicity to define basic geometric elements, such as the point and the line, as "simple" and indivisible.
1st C. BCE - 1st C. CE
Stoic Philosophers
The Stoics valued simplicity in ethics and lifestyle, promoting «ἁπλότης» as a virtue, meaning sincerity and the absence of pretense.
2nd-4th C. CE
Neoplatonists
Plotinus and the Neoplatonists further developed the concept of the "One" as the supreme, simple, and indivisible principle from which all reality emanates.

In Ancient Texts

The significance of ἁπλοῦν is highlighted through philosophical distinctions and definitions.

«τὸ δὲ ἁπλοῦν καὶ ἀσύνθετον καὶ ἀεὶ κατὰ ταὐτὰ καὶ ὡσαύτως ἔχον»
“that which is simple and uncompounded and always remains in the same state and uniformly”
Plato, Phaedo 78d
«τὸ μὲν ἁπλοῦν ἄτμητον, τὸ δὲ σύνθετον μεριστόν»
“the simple is indivisible, while the compound is divisible”
Aristotle, On the Soul 412a
«Σημεῖόν ἐστιν, οὗ μέρος οὐθέν.»
“A point is that which has no part.”
Euclid, Elements, Book I, Definition 1

Isopsephic Words (631)

Words from the Liddell-Scott-Jones lexicon with the same lexarithmos (631) as ἁπλοῦν, but of different roots, offer interesting conceptual parallels.

Ἄπλουν
The capitalized form of the headword itself, highlighting its numerical identity.
ἀντίος
«ἀντίος» means "opposite, facing." Its numerical connection to ἁπλοῦν might suggest the dialectical relationship between simplicity and complexity, or opposition as a means to understand unity.
μετριοπάθεια
«μετριοπάθεια» is moderation, the absence of extremity. This concept aligns with simplicity in avoiding excess and complexity, promoting internal harmony.
ὑπόβλημα
«ὑπόβλημα» means "something thrown under, a foundation." It can be paralleled with ἁπλοῦν as the simple, fundamental principle or the indivisible element underlying any complex structure.
θάνατος
«θάνατος» (death) as the end of life is often interpreted as the ultimate simplification, the dissolution of a complex entity into simpler elements, or a return to an original, simple state.
ἀνάδετος
«ἀνάδετος» means "bound up, tied up, entangled." Its isopsephy with ἁπλοῦν creates an interesting contrast, as the simple is that which is unbound, unentangled, free from constraints.
